PROCESS FOR MAKING BAG-FRAMES.

' Application filed April 16,

To all whom it may concern:

Be it known that I, 'FRANZ A. FULLER, a citizen of the United States,residing in the city of Newark, in the county of Essex and State of NewJersey, have invented a certain new and useful Process for Making Bag-Frames; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make, construct, and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

This invention has reference to improvements in the manufacture offrames for bags and purses, especially for traveling, chatelaine andsimilar bags.

The object of my invention is to overcome present difliculties,dispensing with the numerous constructions heretofore employed forconnecting the pivot members with the main body of the frame section, inorder to produce a bag frame with sharp angular corners, by making aframe from one piece of material, thereby producing a neat, sharp, andsolid corner angle, free from open joints and one in which the crackingor puckering of the metal at the corners ofthe frame during the processof the manufacture of the same, is entirely overcome.

In the accompanying drawings forming a part of this specification,

Figure 1 represents the blank which subsequently forms the bag framemember, pre paratory to channeling the member and making the bend toform the corner.

Fig. 2 illustrates the blank after being channeled and the method ofbending the channeled blank member to form the corner.

Fig. 3 represents a plan View of the same.

Fig. 4 represents a front elevation of a bag frame.

Fig. 5 represents a cross-section of the same; and

Fig. 6 represents a fragmentary view of a portion of the angled blank,illustrating in dotted lines the bend that is given to a portion of thehinge member 9, and a por tion of the main body member h, adjacent tothe cusp e and notch 7.

Similar letters of reference refer to like parts throughout thespecification and draw ings.

In describing the process forming my in Specification of Letters Patent.

vention, I will simultaneously describe the product of the same, so thatthose skilled in the art to which it pertains, may gain a full knowledgeof the product, as. well as of the process.

In Fig. 1, I have shown a sheet metal blank a as it is punched out. Theblank a comprises a main body portion provided at its extremities withapertured ears 6, and along its sides, intermediate of its ends, withdiametrically-oppositely arranged projections 0, which subsequently formthe corners of the bag frame, as clearly indicated in Fig. 4f of thedrawings. To complete the frame members dcZ, with the corner illustratedin the drawings, the blank a is first placed in a suitable die, and thecentral portions of the blank a are channeled along the dotted lines, asshown in Fig. 1, so that a cross-section is as shown in Fig. 5, and aside elevation is as shown in Fig. 2.

It will be seen from an inspection of F ig. 2, that the blank whenchanneled as described, is also simultaneously formed with the cusps e-eon the lower side, and the depressions or notches f-f on the opposite ortop side. After the blank a is channeled and provided with the cusps eand notches f, as heretofore described, the hinge members 9 are bent.The hinge members g g and a portion of the main body member 71. of theblank are bent at right-angles to the main body member h, as illustratedin Fig. 2.

The cusps e-c will be found to contain a sufiicient amount of materialto stretch around the angle of the bend without weakening the same, toform a corner as illustrated, which is so much to be desired in bagframes of the character to which my bag frame relates. At the same time,the notches f upon the opposite outer side of the blank are of suchshape and dimensions so as not to pucker or form ridges during theprocess just described. If it is attempted to bend a straight piece ofmetal such as bag frames are usually made from, it will be found thatthe inner corner will be puckered and covered with ridges, While theouter edge. will have been found to stretch to such an extent as toappear ragged and present a cracked and unsightly appearance.

By the process just described, I am enabled to produce a bag framemember which is composed of a single piece of metal, without the usualopen joints and angled connections, and yet, by the exercise of thisprocess, I am enabled to produce this frame with a minimum of wastematerial, and at the same-time, preserve maximum strength at thehitherto weakened points in the frame.

Having thus described my invention, what I desire to claim and secure byLetters Patent is V The process of forming channeled sheet metal bagframes, consisting in forming" a flat sheet metal blank provided withdiametrically-oppositely arranged projections extending from the edgesof said blank and near the ends thereof, channeling the central portionof said blank longitudinally and simultaneously forming notchesprojecting inwardly from the upper wall of said channeled portion of theblank and cusps adjacent said notches projecting dowmmrdly from theedges of the said Walls of the Cl12l11' neled portions of the blank andbending the ends of the channeled member to form a completed member withdouble rounded corners.
